Abstract

Modeling of Maximum Power Point Tracking Controller for Solar Power System Aryuanto Soetedjo*, Abraham Lomi, Yusuf Ismail Nakhoda, Awan Uji Krismanto Dept. of Electrical Engineering, National Institute of Technology Malang Jalan Raya Karanglo Km 2 Malang, 0341-417635 e-mail: aryuanto@gmail.com* Abstrak Pada makalah ini, sebuah pengendali penjejakan titik maksimum daya (MPPT) untuk sistem pembangkit tenaga surya dimodelkan menggunakan MATLAB Simulink. Model yang dikembangkan dibangun dari modul PV, konverter buck, dan pengendali MPPT. Kontribusi dari makalah ini adalah pada pemodelan konverter buck yang menggunakan pendekatan model persamaan, tidak dengan pendekatan model rangkaian. Model konverter buck yang dikembangkan ini mengijinkan tegangan input konverter, yaitu tegangan keluaran PV, berubah sesuai dengan perubahan siklus kerja, sehingga pada saat terjadi perubahan lingkungan, titik daya maksimum tetap dapat dicapai. Dari hasil percobaan, model yang dikembangkan menghasilkan sifat yang sama dengan model dengan pendekatan rangkaian. Hasil simulasi menunjukkan bahwa model yang dikembangkan dapat mengikuti titik daya maksimum menggunakan algoritma Perturb dan Observe. Kata kunci: algoritma Perturb dan Observe, fotovoltaik, konverter buck, Model Simulink, MPPT Abstract In this paper, a Maximum Power Point Tracking (MPPT) controller for solar power system is modeled using MATLAB Simulink. The model consists of PV module, buck converter, and MPPT controller. The contribution of the work is in the modeling of buck converter using equation model approach rather than circuit model one. The buck converter model is developed using equation model that allowing the input voltage of the converter, i.e. output voltage of PV is changed by varying the duty cycle, so that the maximum power point could be tracked when the environmental changes. From the experiment, the developed model comforms with the circuit model provided by MATLAB Simulink Power Simulation. Furher, the simulation results show that the developed model performs well in tracking the maximum power point (MPP) of the PV module using Perturb and Observe (P&O) Algorithm.
